Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to an ampoule opener for dispensing medicine. Background Technology

[0002] Ampoules are generally colorless and transparent glass bottles. Some ampoules are brown because the drugs are easily oxidized and need to be stored away from light. Ampoules are glass containers used to store liquid medications, such as injectable drugs, vaccines, and serums. To open an ampoule, hold a grinding wheel in one hand and the ampoule in the other. Use the grinding wheel to make a circular cut around the neck of the ampoule, then turn the ampoule so that the nipple is facing upwards, allowing all the medication to flow into the bottle. Finally, pinch the nipple with your fingers to break off the neck of the ampoule.

[0003] In practice, if the ampoule breaks with too much force or the breakage is too severe, it may injure medical staff; it may also slip when the medical staff's hands are sweaty. Utility Model Content

Both the first and second mounting shells have through holes that communicate vertically. A gripping cylinder is rotatably connected to the lower through hole, and a second connecting cylinder that holds the tip of the ampoule is provided in the upper through hole. Cutting components that can move relative to each other are provided on both sides of the first mounting shell opposite to the upper through hole. Pull rods that penetrate the first mounting shell are fixedly connected to both ends of the cutting components, and longitudinal pull rings are fixedly connected to the ends of the pull rods.

[0007] Furthermore, the cutting assembly includes a connecting plate, with connecting blocks slidably connected to the two ends of the connecting plate near the through hole on the side wall of the first mounting shell. A fixing block corresponding to the connecting block is fixedly connected to the bottom end of the first mounting shell away from the through hole. The connecting block and the fixing block are connected by a spring. A groove is provided on the opposite side of the connecting plate, and a rotating grinding wheel is provided in the groove.

[0008] Furthermore, the gripping cylinder includes a rotating ring rotatably connected to the bottom end of the second mounting shell, a first connecting cylinder fixedly connected to the lower end of the rotating ring, and a plurality of airbags disposed on the inner wall of the first connecting cylinder.

[0009] Further, the first connecting barrel and the air bag are both made of elastic rubber material.

[0010] Further, the second connecting barrel is provided with a plurality of equidistant openings, and the second connecting barrel is made of elastic material.

[0011] Further, in the initial state, the distance that the connecting plate moves towards the through hole is the length of the pull rod.

[0012] Compared with the prior art, the beneficial effects of the technical scheme provided by the utility model are as follows: the holding barrel is arranged, so that the ampoule bottle can be prevented from slipping during operation of medical staff; the second connecting barrel is arranged, so that the ampoule bottle nipple with different diameters can be clamped; the cutting assembly is driven to abut against the bottle neck of the ampoule bottle for cutting by pushing the pull rod to make it move relatively.
